Point slope form: y1-y2=m(x1-x2)
Given the slope -4 and the set of coordinates (4,-9),
y+9=-4(x-4)
I plugged in the slope and coordinates. Since -9 came after a subtraction sign, I corrected the subtraction to addition, leaving the above point slope form equation.
I hope this helps :)
Answer:
Equation is [tex]y +9 = -4 (x - 4)[/tex].
Step-by-step explanation:
Given : The slope of the line below is -4 use the coordinates (4 , -9)
To find : find a point slope equation of the line.
Solution : We have given
Slope = -4 .
Coordinates = ( 4 , -9) .
Slope form of a equation of line : [tex]y - y_{1} = m (x - x_{1})[/tex].
Where, m = slope ;
[tex] y_{1} ,x_{1})[/tex] = Coordinates .
We have given m = -4 , Coordinates ( 4 , -9) .
Then equation become
[tex]y - (-9) = -4 (x - 4)[/tex].
[tex]y +9 = -4 (x - 4)[/tex].
Therefore, Equation is [tex]y +9 = -4 (x - 4)[/tex].
